Also described are intermediates useful in carrying out the process for producing such 2-alkanoyl-2-(1-penten-1-yl) cyclohexanones of my invention defined according to the structure: ##STR2## wherein R represents methyl or ethyl.

BACKGROUND OF THE INVENTION

The invention relates to the 2-alkanoyl-2-(1-penten-1-yl)cyclohexanonesof my invention defined according to the structure: ##STR3## wherein Rrepresents methyl or ethyl and uses thereof in augmenting or enhancingthe aroma of perfume compositions, colognes and perfumed articles.

There has been considerable work performed relating to substances whichcan be used to impart (modify, augment or enhance) fragrances to (or in)various consumable materials. These substances are used to diminish theuse of natural materials some of which may be in short supply and toprovide more uniform properties in the finished product.

Jasmine, herbaceous, fatty, smoky, sweaty, and animalic aromas withmyrrh and wintergreen topnotes (particularly those aromas that have ahigh degree of substantivity and a high strength) are desirable in manytypes of perfume compositions, colognes and perfumed articles.

The compounds having the structure: ##STR4## is known to be useful inperfumery. A need exists in the perfume industry to produce thiscompound having the structure: ##STR5## and an attempt was made toproduce it using the compound having the structure: ##STR6## by means ofrearrangement of the double bond into the ring. Such an attempt howevergave rise to unexpected, unobvious and advantageous results yielding thecompound having the structure: ##STR7## as a result of the attempt toreact the compound having the structure: ##STR8## with acetic orpropionic anhydride and then heating the resulting reaction product.

Indeed, nothing in the prior art discloses the compounds definedaccording to the structure: ##STR9## wherein R represents methyl orethyl or the intermediates useful in producing such compounds definedaccording to the structure: ##STR10## wherein R represents methyl orethyl.

Referring to FIGS. 6 and 7, there is provided a process for formingscented polymer pellets (wherein the polymer may be thermoplasticpolymers such as low density polyethylene or polypropylene or copolymersof ethylene and vinyl acetate or mixtures of polymers and copolymerssuch as copolymers of ethylene and vinyl acetate and polyethylene) suchas pellets useful in the formation of plastic particles useful infabricating certain articles which may be perfumed. This processcomprises heating the polymer or mixture of polymers to the meltingpoint of said polymer or mixture of polymers, e.g., 250° C. in the caseof low density polyethylene. The lower most portion of the container ismaintained at a slightly lower temperature and the material in thecontainer is taken off at such location for delivery through theconduit. Thus, referring to FIGS. 6 and 7, in particular, the apparatusused in producing such elements comprises a device for forming thepolymer containing perfume, e.g., polyethylene or polyethylene-polyvinylacetate or mixtures of same or polypropylene, which comprises a vat orcontainer 212 into which the polymer taken alone or in admixture withother copolymers and the perfuming substance defined according to thestructure: ##STR24## wherein R represents methyl or ethyl is placed. Thecontainer is closed by means of an air-tight lid 228 and clamped to thecontainer by bolts 265. A stirrer 273 traverses the lid or cover 228 inan air-tight manner and is rotatable in a suitable manner. A surroundingcylinder 212A having heating coils which are supplied with electriccurrent through cable 214 from a rheostat or control 216 is operated tomaintain the temperature inside the container 212 such that the polymerin the container will be maintained in the molten or liquid state. Ithas been found advantageous to employ polymers at such a temperaturethat the viscosity will be in the range of 90-100 sayboldt seconds. Theheater 218 is operated to maintain the upper portion of the container212 within a temperature range of, for example, 250°-260° C. in the caseof low density polyethylene. The bottom portion of the container 212 isheated by means of heating coils 212A regulated through the control 220connected thereto through a connecting wire 222 to maintain the lowerportion of the container 212 within a temperature range of 250°-270° C.

Thus, the polymer or mixture of polymers added to the container 212 isheated from 10-12 hours, whereafter the perfume composition or perfumematerial consisting of compounds defined according to the structure:##STR25## wherein R represents methyl or ethyl is quickly added to themelt. Generally, about 10-45 percent by weight of the resulting mixtureof the perfumery substance is added to the polymer.

After the perfume material is added to the container 212 the mixture isstirred for a few minutes, for example, 5-15 minutes and maintainedwithin the temperature ranges indicated previously by the heating coil212A. The controls 216 and 220 are connected through cables 224 and 226to a suitable supply of electric current for supplying the power forheating purposes.

Thereafter, the valve "V" is opened permitting the mass to flowoutwardly through conduit 232 having a multiplicity of orifices 234adjacent to the lower side thereof. The outer end of the conduit 232 isclosed so that the liquid polymer intimately admixed with the perfumesubstance defined according to the structure: ##STR26## wherein Rrepresents methyl or ethyl or mixture containing said perfume substancewill continuously drop through the orifices 234 downwardly from theconduit 232. During this time, the temperature of the polymer intimatelyadmixed with the perfumery substance in the container 212 is accuratelycontrolled so that a temperature in the range of from about 250°-260° C.(in the case of low density polyethylene) will exist in the conduit 232.The regulation of the temperature through the controls 216 and 220 isessential in order to insure temperature balance to provide for thecontinuous dropping or dripping of molten polymer intimately admixedwith the perfume materials defined according to the structure: ##STR27##wherein R represents methyl or ethyl through the orifices 234 at a rangewhich will insure the formation of droplets 236 which will falldownwardly onto a moving conveyor belt 238 caused to run betweenconveyor wheels 240 and 242 beneath the conduit 232.

When the droplets 236 fall onto the conveyor 238, they form pellets 244which harden almost instantaneously and fall off the end of the conveyor238 into a container 250 which is advantageously filled with water orsome other suitable cooling liquid to insure the rapid cooling of eachof the pellets 244. The pellets 244 are then collected from thecontainer 250 and utilized for formation of other functional products,e.g., garbage bags and the like.

THE INVENTION

It has now been discovered that novel solid and liquid perfumecompositions, colognes and perfumed articles (e.g., solid or liquidanionic, cationic, nonionic or zwitterionic detergents, fabricsofteners, drier-added fabric softener articles, hair preparations andperfumed polymers) having intense and substantive jasmine, herbaceous,fatty, smoky, sweaty and animalic aromas with myrrh and wintergreentopnotes may be provided by the utilization of one or more of the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention having thestructure: ##STR28## wherein R represents methyl or ethyl in perfumecompositions, perfumed articles and colognes.

The 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention may beproduced by means of reacting the compound having the structure:##STR29## with propionic anhydride or acetic anhydride or a mixedacetic-propionic anhydride defined according to the structure: ##STR30##wherein R and R' are the same or different methyl or ethyl in order toform enol esters defined according to the structure: ##STR31## The enolesters are then heated in the presence of a protonic acid catalyst or aLewis acid catalyst to form a mixture of the two compounds; the compoundhaving the structure: ##STR32## and compounds defined according to thestructure: ##STR33## wherein R represents methyl or ethyl.

The crude reaction product is then separated into its components, forexample, by means of fractional distillation.

More specifically, the reaction sequence taking place may be shown,thusly: ##STR34## wherein R and R' represent the same or differentmethyl or ethyl.

With reference to the reaction between the propionic or acetic anhydridewith the compound having the structure: ##STR35## in order to form theenol esters defined according to the structure: ##STR36## the reactionis carried out at temperatures in the range of from about 50° C. up toabout 180° C., with temperatures in the range of 130°-150° C. beingpreferred. The reaction is also carried out in a solvent such as ahydrocarbon solvent or a chlorocarbon solvent, for example, cumene, asolvent which can be utilized at the reflux temperature of the reactionmass and which can be utilized at the temperature at which the reactioncan proceed.

The mole ratio of acetic or propionic anhydride:compound having thestructure: ##STR37## may vary from about 1:2 down to about 2:1 with moleratios of about 1:1 being preferred.

With respect to the conversion of the enol ester to the product mixturecontaining the compounds having the structures: ##STR38## the reactionpreferably takes place in the presence of an acid, a protonic acid suchas paratoluene sulphonic acid, sulfuric acid or phosphoric acid or aLewis acid such as boron trifluoride, boron trifluoride etherate,stannous chloride, zinc chloride or aluminum chloride or diethylaluminum chloride. The concentration of the acid in the reaction massmay vary from about 1 up to about 5% by weight of the reaction mass.

At the end of the reaction, the reaction products are separated as byfractional distillation; and the resulting reaction products may then beused for their organoleptic properties.

Examples of the 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones useful in thepractice of my invention and their organoleptic properties are asfollows:

                  TABLE I                                                         ______________________________________                                        Structure of The Compound                                                                     Organoleptic Characteristic                                   ______________________________________                                         ##STR39##      A smoky, powerful, sweaty animalic aroma with myrrh and                       wintergreen topnotes.                                          ##STR40##      A jasmine, herbaceous fatty aroma.                            ______________________________________                                    

The 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention and oneor more auxiliary perfume ingredients, including, for example,hydrocarbons, alcohols, ketones other than the ketones of my invention,aldehydes, nitriles, esters, lactones or cyclic esters, syntheticessential oils and natural essential oils, may be admixed so that thecombined odors of the individual components produce a pleasant anddesired fragrance, particularly and preferably jasmine, herbaceous,fatty, smoky, sweaty and animalic aromas with myrrh and wintergreentopnotes.

Such perfume compositions usually contain (a) the main note or the"bouquet" or the foundation stone of the composition; (b) modifierswhich round off and accompany the main note; (c) fixatives which includeodorous substances which lend a particular note to the perfumethroughout all stages of evaporation and substances which retardevaporation; and (d) topnotes which are usually low boiling,fresh-smelling materials.

In perfume compositions, it is the individual components whichcontribute to their particular olfactory characteristics, however theoverall sensory effect of the perfume composition will be at least thesum total of the effects of each of the ingredients. Thus, one or moreof the 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention can beused to alter, modify or enhance the aroma characteristics of a perfumecomposition, for example, by utilizing or moderating the olfactoryreaction contributed by another ingredient in the composition.

The amount of 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my inventionwhich will be effective in perfume compositions as well as perfumedarticles and colognes depends on many factors, including the otheringredients, their amounts and the effect which are desired. It has beenfound that perfume compositions containing as little as 0.01% of the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention or even less(e.g., 0.005%) can be used to impart a jasmine, herbaceous, fatty,smoky, sweaty animalic aroma with myrrh and wintergreen topnotes tosoaps, detergents (including anionic, cationic, nonionic or zwitterionicsolid or liquid detergents) cosmetics, fabric softener articles, fabricwhiteners, optical brighteners and perfumed polymers. The amountemployed can range up to 70% of the fragrance compositions and willdepend on consideration of cost, nature of the end product, the effectdesired on the finished product and the particular fragrance sought.

The 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention areuseful (taken alone or together with other ingredients in perfumecompositions) in detergents and soaps, space odorants and deodorants,perfumes, colognes, toilet water, bath preparations, such as lacquers,brilliantines, pomades and shampoos; cosmetic preparations, such ascreams, deodorants, hand lotions and sun screens; powders such as talcs,dusting powders, face powders and the like. As little as 0.005% of the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention (in theultimate perfumed article) will suffice to impart a jasmine, herbaceous,fatty, smoky, sweaty and animalic aromas with myrrh and wintergreentopnotes to various types of perfumed articles. Generally, no more than3% of the 2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my inventionbased on the ultimate end product (perfumed article) is required. Thus,the range in perfumed articles of the use of the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention are fromabout 0.005% up to about 3% by weight of the ultimate perfumed article.

In addition, the perfume composition or fragrance composition of myinvention can contain a fragrance, or carrier for the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention. The vehiclecan be a liquid such as a non-toxic alcohol, e.g., ethyl alcohol, anon-toxic glycol, e.g., propylene glycol or the like. The carrier canalso be an absorbent such as a gum (e.g., gum arabic, xanthan gum orguar gum), or components for encapsulating the composition (such asgelatin by means of coacervation or such as a urea formaldehyde polymerwhen forming a polymer wall around a liquid perfume center).

My invention also relates to the utilization of controlled releasetechnology for the controlled release of perfumes into gaseousenvironments from polymers such as mixtures of epsilon polycaprolactonepolymers and polyethylene which poly epsilon caprolactone polymers aredefined according to at least one of the structures: ##STR41## wherein"n" is from about 50 up to about 1,200 with the proviso that the average"n" in the system varies from about 150 up to about 700 according to themathematical statement:

    [700≧n≧150]

with the term n being the average number of repeating monomeric unitsfor the epsilon polycaprolactone polymer. The perfumed material'srelease rate from such polymer mixture is close to "zero order". As ageneral rule, the release rate in a polymeric matrix is proportional tot^(-1/2) until about 60% of the functional fluid is released from thepolymeric matrix. The release rate thereafter is related exponentiallyto time as a general rule according to the equation: ##EQU1## wherein k₁and k₂ are constants. According to Kydonieus, "Controlled ReleaseTechnologies: Methods, Theory, and Applications" (cited, supra), theamount of functional fluid released system which are describable asphysically dispersed nonerodible polymeric or elastomeric matrices isproportional to time as long as the concentration of functional fluidpresent (dispersed and dissolved) is higher than the solubility of theagent in the matrix. Thus, such dispersed systems are similar to thedissolved systems except that instead of a decreased release rate after60% of the functional fluid has been emitted, the relationship holdsalmost over the complete release curve. Kydonieus further states, thatif one assumes that the release of functional fluid by diffusion isnegligible in monolithic erodible systems, the speed of erosion willcontrol the release rate and release by erosion by asurface-area-dependent phenomenon, the release being constant (zeroorder) as long as the surface area does not change during the erosionprocess. This is the case with the polymers containing the genus definedaccording to the structure: ##STR42## wherein R represents methyl orethyl.

The polyepsilon caprolactone polymers useful in practicing my inventionis more specifically described in the brochure of the Union CarbideCorporation, 270 Park Avenue, New York, N.Y. 10017, entitled "NEWPOLYCAPROLACTONE THERMOPLASTIC POLYMERS PCL-300 AND PCL-700". Thesepolyepsilon caprolactone polymers are composed of a repeating sequenceof non-polar methylene groups and relatively polar ester groups. Theaverage number of repeating monomeric units varies between 150 and 700depending on the particular "PCL" number. Thus, regarding PCL-300 theaverage number of repeating monomeric units is about 300. RegardingPCL-700, the average number of repeating monomeric units is 700.

The polyepsilon caprolactone homopolymers which are ultimately taken inadmixture with such materials as polyethylene useful in the practice ofmy invention may also be stabilized using stabilizers as defined in U.S.Pat. No. 4,360,682 issued on Nov. 23, 1982, the specification for whichis incorporated herein by reference. The stabilizing materials whichstabilize the polyepsilon caprolactone useful in conjunction with myinvention against discoloration are dihydroxybenzenes such hydroquinoneor compounds having the formula: ##STR43## in which R₁ is alkyl of from1 to 8 carbon atoms, and R₂ is hydrogen or alkyl of 1 to 8 carbon atoms.It is preferable to have such stabilizer in the polyepsilon caprolactonehomopolymer in an amount of from about 100 to 500 ppm. Such stabilizersdo not interfer with the functional fluids dissolved and/or adsorbedinto the polymeric matrix.

The method of incorporating the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention definedaccording to the structure: ##STR44## wherein R represents methyl orethyl or perfume compositions containing same into the polymers may beaccording to the technique, for example, U.S. Pat. No. 3,505,432 issuedon Apr. 7, 1970 (the specification for which is incorporated byreference herein), or U.S. Pat. No. 4,247,498 issued on Jan. 27, 1981,the disclosure of which is incorporated by reference herein.

Thus, for example, a first amount of liquid polyethylene-polyepsiloncaprolactone polymer mixture (50:50) is mixed with a perfume materialsuch as the compound having the structure: ##STR45## Drops are formedfrom the mixture and the drops are solidified. The solidified drops arethen melted, if desired, with a second amount of unscented low densitypolyethylene, for example, polypropylene, for example. Usually, but notnecessarily, the second amount of polymer is larger than the firstamount. The resulting mixture thus obtained is solidified subsequent toor prior to ultimate casting into a utilitarian shape.

Thus, in accordance with one aspect of my invention the imparting ofscent is effected in two stages. In a first stage, a 50:50(weight:weight) polyepsilon caprolactone, e.g., PCL-7009:polyethylene inmolten form is admixed with a high percentage of scent impartingmaterial having the structure: ##STR46## for example, and the mixture issolidified in the form of pellets or beads. These pellets or beads thuscontain a high percentage of material having the structure: ##STR47##(e.g., up to 40% by weight of the entire mixture) and may be used as"master pellets" which thereafter, in a second stage, if desired, may beadmixed and liquified with additional polymers such as additionalpolyethylene and polyepsilon caprolactone in an unscented state, orunscented polypropylene. In addition, additional polymers or copolymersmay be used, for example, copolymers specified and described in UnitedKingdom Patent Specification No. 1,589,201 published on May 7, 1981, thespecification for which is incorporated by reference herein.

In accordance with the present invention the aroma containing material,for example, that having the structure: ##STR48## is added to thepolymer in a large closed container or drum which is maintained undercontrolled temperature conditions while the polymer in a meltedcondition is mixed with the perfume material under agitation.

In order that the perfume be added uniformly to the polymer, thetemperature of the melt is constantly controlled during the process. Thepolymer-perfume mixture is then directed through an elongated conduit orpipe element having a plurality of orifices adjacent to the lower mostportion thereof. The polymer enriched by the perfume is permitted todrip through the orifices onto a continuously moving, cooled conveyorupon which the polymer containing the perfume solidifies into small sizepellets with the perfume imprisoned therein. The apparatus useful inconjunction with this process advantageously includes a conveyor of amaterial which will not adhere to the polymer which contains theperfume. In order that the droplets form into uniform pellets or beads,the conveyor is continuously washed with a liquid such as water tomaintain the surface relatively cool. The pellets are delivered by theconveyor into a container and packaged for shipment.

The following examples serve to illustrate processes for producing the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention (Examples Iand II) as well as processes for utilizing the2-alkanoyl-2-(1-penten-1-yl)cyclohexanones of my invention for theirorganoleptic utilities (Examples III, et seq).

All parts and percentages given herein are by weight unless otherwisespecified.

Two or three bottle capfuls of the above lotion held under the tapreleasing the water into the bathtub yields a copiously foamed bubblebath with no visible precipitation, flocculation, or "bathtub ring" evenusing hard water. Bathing in this bath is found to have a cleansing andpleasing emollient effect on the skin as described above.

When, after immersion in this bath, the body is soaped, rinsed anddried, an even better, more long-lasting emollient, moisturizing effecton the skin is observed. The foam or bubbles are substantiallyunaffected by the soaping step, and no precipitate, flocculate or"bathtub ring", or any bothersome film or coating on the bathtub surfaceis found.

A shampoo of the above composition is made in the following manner.First, the tridecyloxy polyethoxy ethanol is added to a clean mixingtank, with the agitator on, and the amine oxide, polyoxyethylenesorbitan monolaurate and cocomonoethanolamine are added sequentially,with continued agitation. The mix is then heated to 68° C., until thecocomonoethanolamide is melted and/or dissolved. The hydrogen peroxidesolution is then admixed with the mentioned nonionics and mixing iscontinued for about half an hour, in which the peroxide destroys anyfree amines or other harmful impurities that may be present. The mix isthen cooled to 38° C.

In a separate mixer the polyacrylamide is gradually added to the formulaweight of deionized water, with the mixer on. Addition is effectedcarefully and slowly (the polyacrylamide is sprinkled in) to avoid theproduction of "fish eyes" in the mix. After dissolving of thepolyacrylamide the solution thereof is added to the first mixing tankwith agitation and is blended with the nonionics, such mixings being atroom temperature. Subsequently the perfume as indicated in Table II ofExample IV, supra, giving rise to the aroma profile as set forth inTable II of Example IV, supra, is admixed with the balance of thecomposition and mixing is continued for another half hour.

The product made is an excellent shampoo of satisfactory viscosity andaroma, foaming power, foam stability, low conductivity and goodshampooing effects. The viscosity is about 1,000 centipoises at 20° C.and the conductivity, using the Hach Conductivity Meter, is 750micromhos/cm. The foaming power is 250 ml and the foam stability is 22seconds, by the test method previously described. In comparison, acommercial shampoo based on triethanolamine lauryl sulphate detergenthas a conductivity of about 22,000 micromhos/cm, a viscosity of about1,500 centipoises, a foaming power of about 380 ml and a foam stabilityof 60 seconds.

In panel evaluations of the experimental shampoo compared to a differentcommercial product, in actual shampooing, the experimental formula wasadjudged significantly better in being less drying, producing a softerfeel for the wet hair, leaving the wet hair easier to comb, being lessprone to accumulate static charges (less flyaway) and having a foam ofbetter appearance and feel. Additionally, the experimental product wasjudged better in almost all hair effect properties, with the controlonly being about equal to it in curl retention. In properties other thanthose mentioned the experimental product was better in rinsability, thecontrol was better in foam build-up rate and the foams were about equalin volume and stability.

In the shampooing described herein and in subsequent Examples the humanhair is washed on the head by wetting the hair with warm tap water atabout 42° C., applying 15 grams of shampoo to the hair, lathering itinto the hair for a minute, rinsing with warm tap water for 30 seconds,re-lathering with 7 grams of shampoo for a minute and rinsing off for 30seconds, after which the hair is towel-dried and dried further with anautomatic hair dryer.

No.4,000,080 issued on Dec. 28, 1976, (the specification for which isincorporated by reference herein) is intimately admixed with 0.15 gramsof one of the perfume materials of Table II of Example IV, supra, untila substantially homogeneous composition is obtained. The composition hasan aroma as set forth in Table II of Example IV, supra.

EXAMPLE X

Each of the fragranced materials of Table II of Example IV, supra, areadded to a 50:50 weight:weight mixture of low densitypolyethylene:polyepsilon caprolactone PCL-700 forming pellets withscents as set forth in Table II of Example IV, supra:

75 Pounds of a mixture of PCL-700 polyepsilon caprolactone (manufacturedby the Union Carbide Corporation of New York, N.Y. having a meltingpoint of about 180°-190° F.): Low density polyethylene are heated toabout 250° C. in a container of the kind illustrated in FIGS. 6 and 7.25 Pounds of each of the fragrance materials as set forth in Table II ofExample IV, is then quickly added to the liquified polymer mixture, thelid 228 is put in place and the agitating means 273 are actuated. Thetemperature is then raised to about 260° F. and the mixing is continuedfor 5-15 minutes. The valve "V" is then opened to allow flow of themolten polymer enriched with perfume ingredient to exit through theorifices 234. The liquid falling through the orifices 234 solidifiesalmost instantaneously upon impact with the moving cooled conveyor 238.Polymer beads or pellets 244 having pronounced scents as described inTable II of Example IV, supra, are thus formed. Analysis demonstratesthat the pellets contain about 25% of the perfume material so thatalmost no losses in the scenting substance did occur. These pellets maybe called "master pellets".
